Well, the difference between uniform and sculptured SA is not that dramatic, IMO. It is obvious when you look closely at two keyboards side-by-side, but in actual use I don't feel a dramatic enough difference to be distracted by it. The difference can also be mitigated a bit by keeping the feet folded in when using sculptured SA and pulling the feet open when using uniform. That way you get a similar angle in either case (not identical, but similar so as to reduce the difference in row heights).
